Dhcp And Static Ip Addressing; Hp D2D On A Gigabit Ethernet Network; Connecting To A Business Server On The Main Network - HP StorageWorks D2D - Backup Systems User Manual

DHCP and static IP addressing

DHCP network addressing is enabled by default as long as you are connecting the HP D2D as an
IPv4 device; this means that an IP address and other network settings are assigned automatically
when you connect the HP D2D Backup System to an IPv4 network that has a DHCP server. If preferred,
you can use static IP addressing and assign settings manually during the installation process. If you
are connecting to an IPv6–only network, it is normally sufficient to enter the IPv6 MAC Address (found
on the label on the top of the unit) when running the Installation Wizard.
The HP D2D Backup System should be on the same logical and physical network as the host machine
connecting to it. This is normally the case because, typically, the HP D2D Backup System is connected
to the same Gigabit network switch as the host machines backing up to it.

HP D2D on a Gigabit Ethernet network

The HP D2D Backup System is connected to a spare port on an existing Gigabit network switch.
This may be your main network, which is also used to connect a number of different types of devices,
such as PCs, servers, workstations and printers, or a dedicated backup network that is used solely
for clients that need to be backed up.
The configuration, illustrated in
assuming that Gigabit networking is already in place, and requires no additional hardware. The only
disadvantage to the configuration is that a high volume of traffic may impact network performance
during backup and backups may take longer to complete. However, if backups are scheduled to run
outside of normal business hours, the volume of data traffic is unlikely to be a problem.

In some environments, backup data is kept separate from day-to-day office network traffic, as illustrated
in Figure 14 on page 39. There is a separate, dedicated IP network for all hosts that need data to
be backed up.
